1. Calculate price rate of concrete for 1 cubic meter if: a) Concrete mixed with hand power b) Concrete is mixed with concrete mixer (rental) Information: Reinforcement concrete (1: 1 1/2: 3 – 13 mm aggregate) Material -1 bag Portland cement = RM 8.60 - (28.4 bag is used) -1 cubic meter sand = RM 32.00 -1 cubic meter aggregate size 13 mm = RM 40.00 Labour (hand power) - Time taken for mixing concrete = 3 hour / cubic meter - Labour wage for 1 day =RM 18.00 - Working time for 1 day 8 hour Profit = 10% Machine -Concrete mixer machine a) Capability 7/5 - 1 hour produced 4 cubic meter concrete b) 4 labour handle the machine Assume: Actual price for concrete mixer machine = RM 3500.00 Capital Cost Interest machine (let say 5% per year for duration 5 years) • Maintenance cost for the duration 5 year (normally 1/10 from original machine price) Transportation cost machine for the duration 5 years from one construction site to another construction site (normally 1/20 from original machine price) Operating Cost Operator concrete mixer work 8 hour in 1 day = RM 18.00 Labour wage (by using concrete mixer) = RM 2.00 per hour Material: - 6 liter diesel used for 1 day (1 liter RM 1.00) = RM 6.00 - Lubricant oil = RM 1.00 %3D 1.
